To all whom it concern:

. Be it known t at 1,.THOMAKS OHALMERS GRANT, a subject of GreatBritain, and resident of New Glas ow, in the county of Pictou, Provinceof ova Scotia, Canada, have invented certain new and useful Improve-I'nents in Fountain-Pens, of whichthe folfountain-gens and to remedycertain objections inei ent to fountain-pens as atpresent constructedand used.

Fountain-pens as heretofore constructed have been equi ped with a cap toprotect the pgn-point, an this cap when the pen is to put into use, isremoved from the point of the pen and applied on the outer end of theholder. After the use of the pen the 0:1: is removed from the outer endof the hotter and carefully restored to position over the point of thepen. My invention dispenses entirel with this cap and provides aslidable tu ular casin encompassing a portion of the length of t een-holder and equipped with means for loc ing or retaining 1t in suchgiven position as may be desir-edon the holder, whereby only the penoint and adjacent part of the holder may e exposed when it is desired touse the pen in writing and whereb also an increased portion of thepen-hol 'er may be exposed when it is desired to remove the socket endof the pen-holder for filling thefountain with ink. The casing is alsoprovided with a self-closing lid at one end and also with a concealedspring for moving it to its initial 7 or protecting position when itslocking device is released to permit the spring to act.

The nature of the invention and the means for carrying the same intoefi'ect will be fully understood from the detailed descriptionhereinafter presented, reference being had to the accompanying drawings,in

Figure 1 is a central vertical section, partly broken away, on thedotted line 1-1 of Fig; 2, of a pen-holder equipped with an exteriorcasing and cooperating parts embodying my invention, the casing beingshown m the position it will occupy when it Specification of LettersPatent.

. is desired to employ the pen for writing purposes; Fig. 2 is anelevation of the same, taken from the right hand side of Fig. 1 andshowing the exterior casing in the position it occupies when it is usedfor protecting the en-point, said casing having moved upward y from theshown in Fi 1 an its hinged end piece .having close over the pen-point;Fig. 3 is a view corresponding with Fig. 2 but showmoved downwardly toits extreme outer posit on so as to expose the socket for the penpointpreparatory to the removal of the with ink, and Fig. 4 is a view of thepensocket removed from the holder.

In the drawings, 10 designates a fountainpen holder having a pen-socket11 and pen 12, all of usual or any suitable construction with theexception of such changes in the exterior surfaces thereof as becomedesirablein carrying out my invention.

The exterior casing or protector for the pen is numbered 14 and is inthe form of a tubular shell which is less in length than the length ofthe pen-holder and is slidable is uppermost when the pen is in use, thecasing 14 is provided with a spring-dog 15 of any suitab e constructionfor engaging,- when it is-s'o desired, one or the other of the recesses'16 formed in the barrel of the holder 10. The engagin end of the dog 15passes through a hole '1 in the casin 14 and is spring-pressed againstthe holder 10, and

with said end of said dog, the latter will become engaged with theholder and lock the casing 14 in fixed position thereon. The oppositeend of the casing 14 is cut off on an inclined line approximating theinclination "of the side edgesof the pen-point and to cover this end ofthe casing 14 so as to conceal at the proper time the pen-point, Iprovide the casing with a bin ed end-piece or cover 18 adapted to fitagainst the edges of the end of the casing and to close said end, asshown in Fig. 2. The cover 18 will preferably be used in connection witha spring the casing moves to its protecting position shown in Fig.- 2and to place a tension on said cover when the casing is away from itsprotecting position, as shown in Figs. 1 and 3", whereby said cover iskept pressed lightly Patented Sept.

ing the inclosing casing as having beensame for enabling the fountain tobe filled hence when either recess 16 passes into line osition in whlchit is i thereon. At its outer end or that end which 19 for automaticallyclosing the same when against the pen-holder and prevented from swingingloosely.

It is my intention that the casing 14 shall remain a permanent art ofthe pen-holder and also that it shal have a spring action tending tomove it to its protecting position, shown in Fig. 2, and to this end Iprovide within the casing a coiled spring 20 which at one end bearsagainst an interior annular shoulder 24 on the casing and at its otherend against a shoulder 22 formed on the holder 10. I also provide thecasing with a screw 21 whose inner end enters a longitudinal groove 23formed in the holder 10, and said screw and groove cooperate to preventthe holder from turning within the casing or the casing turning on theholder and also to limit the endwise movement the casing may have on theholder. When the casing 14 is in its protecting position, shown in Fig.2, the point of the screw 21 is at and becomes arrested by the end-wallof the upper end of the groove 23, and at this time the spring 20 willexert a sufficient tension against 'the shoulders 22, 24, to maintainthe relation of the casing and holder with proper firmness. \Vhen thecasing 14 is in the position shown in Fig. 2 the pen-point will be wellprotected by the casing and its cover 18 and the pen may be carried inthe pocket as usual. When it is desired to use the pen, the penholdermay be withdrawn from the pocket and have its outer end placed on atable or other support and thereupon, the user only employing his onehand for the entire operation, the casing 14 may be pressed downwardlyalong the holder 10 and against the stress of the spring 20 to theposition in which said casin 1s illustrated in Fig. 1, upon reachingwhlch position the casing will become locked by the engagement of thedog 15 with the inner recess 16. The pen will then be ready for use, andwhen it is desired to restore the pen-holder to the pocket again, theuser will simply release the dog 15 so as to enable the spring 20 by itsexpansion to slide the casing and holder into the relation in which theyare shown in Fig. 2, the casing passing beyond the point of the pen andthe cover 18 automatically closing over said point.

During the ordinary employment of the pen, the casing 14 will be at itsintermediate position, shown in Fig.- 1, with the pen-point exposed forwriting purposes, said casing being locked in such position by theengage-i ment of the dog 15 During the period that the pen-holder iscarried in the pocket or laid away, the casing 14 will be in itsprotecting position shown in Fig. 2. When it is desired to re-. more thepen-point socket and fill the holder with ink, the exterior casing 14will he slid downwardly on the holder 10 until thedog 15 reaches andengages the outer recess 16 with the lnner recess 16.

or to the position shown in Fi by ressing on the exposed en l of thedog, ena lin it to pass by the inner recess 16. When t 1e casing is inits extreme position shown in Fig. 3, the socket 11 becomes exposed andmay be removed and the holder filled with ink, and thereupon after thesocket is restored to the holder, the owner of the pen may release thedog 15 and per mit the spring 20 to restore the casing 14 to itsprotecting position shown in Fig. 2 or only to its intermediate positionshown in Fig. 1, leaving the pen-holder in condition for immediate use.ably be slightly convex on its inner face, and during the movement ofthe casing 14 in a direction from the pen-point the penpoint does notstrike does the lid strike against the pen-point, when closing the outerend of the casing 14, the edges of the socket for the pen being utilizedfor forcing the lid 18 to its open position and for receiving thepressure of the lid 18 during its closing movement.

The casing 14 answers as an entire substitute for the customary capsused on fountain-pen holders and constitutes a permanent part of theholder. The casing 14 is merely slid on the pen-holder when moved to itsseveral positions and it may be operated with entire ease by one hand.

What I claim as my invention and desire to secure by Letters Patent, is:

1. In combination, a fountain penholder, a casing slidably mountedthereon having a closing cap at one end for protecting the pen-point, aspring normally acting to move said casing to its initial protectingposition, and means for locking said casing when slid on the handle toexpose the pen-point; substantially as set forth.

2.
